Re: [aspectwerkz-user] Advice weaving problem when using hot deployment w/ annotation

Hi Vincent

Your project does not contain any aop.xml file.
Even with hot deployment, one such file must be there.
In that file you have two options:
- declare the aspect that you will hotdeploy / undeploy (deployed at
startup) using the usual <aspect class=../>
- declare a <deployment-scope where you say : at that place I do allow
aspect deployment / undeployment (whatever the aspect is)

If you are using a deployment-scope, you can then use the Deployer API
to deploy at that scope. There should be some sample around else it is
probably like that :
SystemDefinitionContainer.getDefinition(uuid,
ClassLoader).getDeploymentScope(scopeName)

There is no hotswap occuring in your current app, since the scope was
empty and there was no aspect declared.
Also, does the maven build magic handle AnnotationC ?
(PS: can't you play with Java 5 - that s much easier)
